A new approach towards the early recognition of H-induced stress corrosion

Abstract
The investigation show that diffusion of hydrogen into ferritic steel leads to changes in the micromagnetic properties of the material. This can be explained by the interaction of the magnetic structure with locally occuring fields of residual stresses. In principle, an early recognition of H-induced stress corrosion cracking is thus possible.
